    The maneuver is identified by a leg index and step index, in case the route doubles back on itself.

    Declaration

    Swift

    func polylineAroundManeuver(legIndex: Int, stepIndex: Int, distance: CLLocationDistance) -> LineString

    Parameters

    legIndex

    Zero-based index of the leg containing the maneuver.
    stepIndex

    Zero-based index of the step containing the maneuver.
    distance

    Distance by which the resulting polyline extends in either direction from the maneuver.

    Return Value
